No, not really.
Not only do you not understand, you don't even realise that you don't understand and you're not even
trying to understand. So I'm not really sure why you even posted here in the first place.

I'll just give up after this.
You stated:
>Bitches due date is tomorrow from 1st tie or Monday from 2nd tie
That statement only demonstrates that you don't understand. When she was mated makes no difference to when she is due. The only thing that matters is when she ovulated. She could have been bred 6 times or just once, 3 days earlier than she was or 4 days later. It makes no difference. You can't calculate anything from breeding dates.
If you are making statements about her due date in relation to
breeding dates, you are demonstrating that you don't understand this key concept.
You are then STILL saying:
>Her results told me she is due today or tomrrow end of.
Er, no. You're just repeating what you said to start with and still don't get it and are missing the point

Look, it's impossible for anyone to help you unless you give the
actual dates and the
actual numerical results of your progesterone tests. Even with those, there may not be enough information if you only tested twice, but there might be. If you can't give those, then we can't help you.
You need to go to the vet if you get to day 65 FROM OVULATION without any puppies. That's not day 65 from first breeding or 2nd breeding or anything else - it's from OVULATION.
